I think they are pretty cool, myself. It's neat to watch the way the move and eat. I think most people would call fish in general boring, but I think they all have something to offer. I love having shrimp, myself.
Ghost shrimp are great pets. I just love watching them in my oscar tank.
30 shrimp into the tank and 2 days later I get to buy shrimp all over again.
While they're in there before my oscar finds them they're busy little critters I'll tell you that. I've been tempted to try them in my tropical tank though I have a feeling that my clown loaches would devour them.
